Antti-Teollisuus announced Finland's largest grain silo

The giant silos of Antti-Teollisuus quadruple grain storage capacity

Thanks to their completely domestic product development and large investments, Antti-Teollisuus Oy brings giant-sized grain silos to the market. The new Iso-Antti grain silos with their quadrupled capacity lower storage costs significantly.

The first grain silos erected as a pilot project were completed this summer and the official announcement event was held on 31 August 2022. 

The benefits of a giant silo

The domestically-produced Iso-Antti silos, designed for northern conditions, take grain storage to the limit. The volume of one Iso-Antti, depending on the number of layers and accessories, is somewhere between 732 and 1,911 cubic metres. The diametres of the Iso-Antti grain silos are 10.6 and 12.1 metres.

A single large silo, compared to several smaller silos, produces a more favorable price per cube for grain storage, because the investment cost per cube of grain decreases. It also requires less foundation work. The filling and emptying devices of the large silo are significantly more efficient in capacity.

It has previously been possible to order silos of a similar size from Europe and North America. Finnish production eliminates massive freight costs from abroad.

Enlarging the silos has not been a simple project

Special-purpose steel is needed for the new silos, and a completely new production line with equipment has been built for its processing. 

“The project started with a clean slate. All strength calculations and manufacturing plans were completely remade”

says Jouni Virtaniemi, Commercial Manager of Antti-Teollisuus.

The duration of the project from product design and building the production line to the erecting of the pilot sites and testing and launching the products has lasted 2.5 years. 

First deliveries in 2023

Orders are already being accepted and deliveries will start in 2023.
